JAMES E. MAYNADIER, OF TAUNTON, ASSIGNOR TO THE BUSELL TRIMMER COMPANY, OF BOSTON, MASSACHUSETTS.

. ROTARY CUTTER.

SPECIFICATION forming part of Letters Patent No. 380,338, dated April 3, 1888.

Application filed January 23, 1884. Serial No. 118,491. (No model.)

To on whom it may concern:

Be it known that I, JAMES E. MAYNADIER, of Taunton, in the county of Bristol and State of Massachusetts, have invented an Improvement in Rotary Gutters, of which the following is a specification, reference being had to the accompanying drawings.

Figure 1 is a section through the axis of the cutter, and Figs. 2 and 3 are cross-sections on line a: x of Fig. 1, the first looking to the left and the other looking to the right, illustrating one form of cutter embodying my invention; and Fig. 4 is a perspective view of part of the guard,whioh is the main feature of my invention.

In rotary cutters as now used for trimming sole-edges the office of the guard,which is to prevent the teeth of the cutter from taking too thick a chip-that is, to prevent too much ranknessis performed by the outer end of each tooth.

My invention is a novel rotary cutter made up of a hub having a series of cutting-teeth integral with it, and another hub having a series of integral guard-teeth, one hub receiving the other, so that the guard and cutting teeth are brought into and locked in proper relation to each other.

In the drawings, 1) is a hub having a series of integral guard-teeth, and f is a hub having a series of integral cutting-teeth, d. The hub f has a lateral annular groove to receive hub b,which is slid into the groove, (see Fig. 1,) so that the guard-teeth a lie between the cutting-teeth d, as plainly shown in the drawings. Hub 1) is secured to hub f by a setscrew, i, to prevent the guard from working laterally out of the cutter. The rotary cutter thus formed is mounted on shaft h, the screw h preferably holding the rand-guide gin place and the cutter upon the shaft in the usual way.

What I claim as my invention is- The rotary cutter consisting of hub f,having integral teeth 11, in combination with a guard consisting of hub I), having integral teeth a, the two hubs f and b fitting together-,so that the guard-teeth a alternate with the cutting-teeth d,substantially as and for the purpose set forth.
